The last few Tarantino films have been pretty big budget, so I think whatever Tarantino wants, Tarantino gets. Despite the apparent excesses of Tarantino's films, you can tell they're very tightly plotted, edited to near perfection, and most importantly, Tarantino has a gift for a dialogue that Lucas never had.
I'm a big fan of Q's earlier films, but I'm not so impressed with his last few.
I really wish I'd seen Grindhouse in its original form. Instead, I saw Death Proof, which was padded out into a feature film - and I thought it showed. The tight plotting, pacing, and editing just weren't there. Instead, there was entirely too much of his trademark dialogue.
Inglourious Basterds had its moments, but was largely forgettable. And while Django Unchained was gorgeously shot, its story paled in comparison to one of its influences, Mandingo.
I'm hoping that Hateful Eight will be back on track. Meanwhile, I think that it's time to watch Jackie Brown again.
